Still having problems with blue screen during bootup. I installed 7.31M - latest version. It seemed to run fine yesterday all day but today when I booted up I could get past blue screen. Disconnected USB HP hub and all is well. I have upgraded my graphic adapter and USB Host ctrlr to latest versions. Open for any more suggestions before I try to downgrade back to a version that worked with my config. I think it was pre 7.0.
Thanks!
